Specification forming part of Letters Patent N0. 50,361, (lated Octoberl0, 1865.

To all whom fit 'may concern: V

Be it known that I, HENRY JEFFREY, ot' Vincennes, in the county of Knoxand State ot' Indiana, have invented a new and Improved Device forDrawing Spikes; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to theaccompanying drawings, forming part- Of this specification, in which-Figure l is an edge view of my invention; Figs. 2, 3, and 4, side viewsof the saine; Fig. 5, a detached plan or top view ot' a plate pertainingto the same; Fig'. 6, a detached view ot' a lever pertaining to thesame.

Similar letters ot' reference indicate like parts.

This invention relates to a new and improved device for drawing spikesand bolts, and is designed for general use, having for its object thedrawing ofthe spikes or bolts without bending them, so that they maybeused again after being drawn.

The within description refers to the in vention being used for drawingrailroadspikes.

A represents a semicircular frame or shoe, which may be termed a movableor rolling fulcrutn,77 having on its upper or straight side, a, aplate,B, provided with a steady pin or bolt, I), which tits into the side u.Each end of this plate B has a notch, c, made in it, and these notchesare in line with grooves d, made in the ends of the semicircular fulcrumA, said notches and grooves forming claws to catch under the head of thespike or bolt to be drawn. This plate may be dispensed with, the endsot' A serving alone as claws; but the plate B is preferable.

C represents a handle or lever, which is attached to the semicircularfulcrnm A by means of two short bars, D D, which are secured at one endto opposite sides ot' the lever O by a bolt, e, said bars extendin gdown, one at each side of A, and having holes made in them,

through which a key,E,is driven, to clamp the lever firmly to thefulcrnnn A, the key E being driven between the under or inner surta-ceot' a and a plate,f, fitted in the bars.

The handle or lever O may be secured to the t'ulcrum A in two differentpositions, as shown in Figs. 2 and 3, at right angles with thestraightside a., as shown in Fig. 2, and parallel with said side, asshown in Fig. 3. When the lever is adjusted as shown in Fig. l thedevice is used for drawing spikes at the outer side of the track, thelever O being raised from a horizontal toward a vertical position. Whenadjusted as shown in Fig. 8 the device is used for drawing spikes insidethe track, the lever being forced down from a vertical to a horizontalposition, the operator in both cases standing within the track onbridges or trestles of any kind.

The lever O' (shown in Fig. 4) has a beveled lower end, which gives itan inclined position when secured to the fulcrum. This may be used as anindependent pinch-bar when there is no bridge or trestle, and forgeneral work when attached to A.

The plate B may, it' worn by use or injured inv any way, be replaced bya new one at any time.

The device is not liable to get out of repair, and possesses theadvantage ot' drawing spikes without bending or injuring them, and byllaving duplicates of the parts there will be no necessity ot' sendingthe device to a shop tor repairs in case ot' breakage.

I cla-im as new and desire to secure by Letters Patent- The semicircularrolling` fulcrum A, in connection with the handle or lever O, and hingedbars D, and either with or without the plate B, all arrangedsubstantially as and t'or the purpose speciiied.
